When the guard is positioned as shown in Figure 1 and the journal box and axle are kassembled, pad Il is thrust rearwardly by spring II so that the pad contacts the inner face of the journal rear wall 4. At the same time, the pad is thrust upwardly by springs I6 so that the upper edge of the pad contacts the periphery of axle just inside of box wall 4. Pad 22 is thrust rearwardly and upwardly by springs 2| so that its upper edge is thrust against llet F. Pads I'I and 22 are mounted to move independently of and relative to each other in various directions so that they may be thrust tightly against the journal axle and the box rear wall, irrespective of variations in the sizes of the journal and axle, or in the spacing of llet F from the box rear Wall due to variations in dimensions of the axle, journal and box and variations in the play of the axle lengthwise of the box. In other words,

.pad 22 can follow the journal in its movements vertically, transversely or longitudinally of the box without affecting the contact of pad l1 with the axle and the rear wall of the box and the edge of pad 22 is not broken or worn down unduly because of the above-mentioned movement of the journal as would be the case if pad 22 were iixed in respect to pad lI.

The oil guard is readily applied and removed from the journal box as a unit and the individual pads of the oil guard may be assembled and disassembled for replacement or repair. The smaller pad 22 acts as a wiper to remove surplus oil flowing to the right along the lower portion of the journal and the larger pad I1 and seals the gap between the axle and the edge of the axle opening in the journal box rear wall and prevents the ow of any oil to the right which is not caught by pad 22.

The pads may consist of wood or other fibers rather than felt and the detaiis of the mounting of the pads may be varied substantially from those shown without departing from the spirit of the invention and the exclusive useof those modications coming within the scope of the claims is contemplated.

What is claimed is:

l. In an oil guard for a railway axle journal box, a horizontally disposed support plate, an upstanding plate, hinged structure mounting said upstanding plate on said support plate, a supplemental upstanding plate hinged on said upstanding plate, said structure including spring means thrusting said upstanding plates upwardly and rearwardly of said support plate, and individual pads of fibrous material mounted on said upstanding plates with their upper edges shaped to fit the contour of a railway journal and adjacent axle portion.

2. In an oil guard for a railway axle journal box, a horizontally disposed support plate, a plate extending upwardly therefrom, a torsion spring having a radial arm Vat one end anchored to the support plate and a radial arm at its other end secured to the upstanding plate, said spring providing a hinge assembly for the two plates, a carrier slidable vertically along one side of said upstanding plate, a fibrous pad on said carrier arranged for contact with a portion of an axle to which the guard is applied, a supplemental carrier hinged to the opposite side of said upstanding plate, and a pad of fibrous material mounted on said supplemental carrier, there being yielding means thrusting both of said carriers and the associated pads away from said support plate.

3. An oil guard as described in claim 1, in which the mounting for the rst-mentioned upstanding plate includes means providing for the swiveling of said upstanding plate on said support plate about an upright axis.

4. In combination with a railway axle journal box having a bottom wall and a rear wall, an associated axle and journal, a holding rplate adjacent the bottom of the box and having slots near the rear end of the box, an oil guard device including a support with depending tongues inserted in said slots to position the device on the holding plate when the support is at rest while accommodating their ready disassembly when the support is tilted, an upstanding pad of fibrous material having a mounting on said support which accommodates the movement of said pad into contact with the inner face of the rear wall of the box and the movement of the upper edge of said pad into contact with an axle upon .which the box is mounted, an upstanding pad of nbrous material spaced from said rst-mentioned pad and having a mounting associated with said first-mentioned mounting which accommodates movement of the associated pad upwardly and longitudinally of the box relative to the first-mentioned pad.

5. Structure as described in claim 1 in which the mounting for the first-mentioned pad may swivel on the holding plate at an angle to its hinge movement and the mounting for the second-mentioned pad is carried on the mounting for the first-mentioned pad.

6. In an oil guard for a railway axle journal box, a pad with an arcuate upper face disposed to engage a journal to which the guard is applied, and a pad with a similarly arcuate upper face having a dierent radius, a common support, a device for pivotally mounting one of said pads on said support, and structure independently pivotally mounting the other of said pads on said device, there being individual means yieldingly thrusting said pads about their pivotal mountings and upwardly away from said common support, and stops limiting the action of said means.

7. In an oil guard for a railway axle journal box, a support member, a pair of wide, relatively thin pads of fibrous material with their upper edges comprising concave arcs of diierent radii, a device mounting one of said pads on said support and yieldingly thrusting the same edgewise and away from said support, means pivotally mounting the other of said pads on said device and yieldingly thrusting the same edgewise away from said support and angularly towards the other pad.

8. In combination with a railway axle journal box, having a bottom wall and a rear wall, and an associated axle including a main portion and a journal of smaller diameter, there being a llet between said journal and portion, a pair of relatively wide, thin pads of fibrous material extending transversely of the axle axis and having arcuate upper edges with different radii corresponding to the radii of said illet and portion, respectively, structure mounted on the box bottom Wall and yieldingly thrusting the pad with the larger radii upwardly against said portion, and a device pivoted on said structure and yieldingly thrusting the pad with the smaller radii angularly upwardly against said fillet.
